To 171 ich/Nit it inf/ty concern:

Beit known that we, CHARLES L. GoiiHRiNG and lifinLL-iii Timoria, bothJ ot' Akron, in the county of Summit and State ot' Ohio, have invented certain new and useful improvements in Glass-Grinding Machines; and we do hereby declare the following to be a full, clear, and exact description o'i' the saine, reference being had to the accompanying drawings, forming a part of this specification, and to the figuresand letters of reference marked thei'eon.

rhis linvention relates to glass-grinding machinery, and particularly to machinery for lieveling glass plates by a grinding process, the objects of the invention being to provide an improved mechanism for holding the glass during its presenta-tion to the grinder with means whereby the adjustments necessary for making bcvcls'ot' different depth and width are facilitated.

i further object of the invention is to sinia plify the mechanical structure whereby the partsniay be made ot' sutiicient strength to withstand the pressure of a forced grinding operation without disturbing` the adjustments necessary for accurate work.

'ihc invention consists in a glass-holding mechanism pivoted on an axis substantially coincident with the inner edge of the bevel, with means whereby said axis may be adjusted in the direction of the width votl the bevel combined with means whereby the angular position ot thel glass about said axis may bc adjusted to vary the depth oi the bevel.

'l`he invention further consists in a glass clamping and holdingmechanism mounted on a pivotal axis substantially coincident with the inner edge ot' the bevel, with means whereb v the angular position of the glass may be adjusted to vary the depth oi bevel without variation ot' the width.

The invention l'urther consists in certain novel details ol construction and combinations und arrangements ot' parts, all as will beiiow described, and pointed out particularlyin the appended claims.

Referring to the accompanying drawings, Figure l is a vertical section through a machine t'or bcvcling glass embodying the presen t improvements, certain portions of the operating mechanism being shown in elevation and other portions not directly related to the present improvements being omitted. Fig. 2 is a detail side elevation with parts in 'section and partly broken away, showing the grinder and adjusting mechanism for the pivot or axis ot' thc glass-holding devices. Fig. is a sectional elevation looking toward the left oi' the parts shown in Fig. 2. Fig. L isasectional top plan View of the same. Fig. 5 isa 6J View corresponding to Fig. 2, but showing a clamping and holding mechanism adapted for., the presentation of the glass to the upper surface of the grinder. Fig. 6 is an' elevation of the parts illustrated in Fig. 5 looking toward 65 the left.

Like letters and ligures of reference in the several iigures indicate the same parts.

Referring to Figs. l to .t, the letter O indicates a rotarygrinder adapted to be rotated by any forni ot driving mechanism and preferably mounted on ways O3, so as to be capable of a bodily traverse in the plane of the. bevel to be formed. The traverse movements of the grinder are imparted thereto b y a crank D', connected with the grinder-bearings through the medium ot' connecting-rods l), appropriate mechanism forming no part of the present invention being employed for oscillating the crank D' to the desired extent. 8O A frame K', vertically adjustable in the machine-frame by means of screws K2, shaft K3, bevel-gears 1C, and hand-wheel K", is provided with forwardlyeiitending arms K, in the ends ot' which the journals for the glass- 85 holding mechanism are mounted. This giassholding mechanism consists, primarily, of a bed l, having arms K journaled in the arms KG and adapted to be angularly adjusted about its pivotal point by proper mechanism, and a coiiperat-ing clamp L, pivotal'ly mounted on its support, so as to be capable ot' conforming to the angular position of the bed or surface ot' the glass being clamped against the bed. The mechanism for adjusting the angular position ot' the bed (illustrated in Fig. 1) consists of a screw K, journaled in the traine l' and cooperating with a screwforay n these :s hoid- 70 mounml on ance is 75 amgw is dexie the position of I D of S in the fo1-- mme screw in t The u n md :und
